WRAPPER FOR PACKING ELECTRIC-LIG-HT BULBS.

Application filed August 28, 1919.

To all whom it may concern:

Be it known that we, JAMES E. OLENNY and Gnonen S. VVnien'r, citizens of the United States, residing, respectively, at New York city, county of New York, and State of New York, and La Grange, county of Cook, and State of Illinois, have invented certain new and useful Improvements in \Vrappers for Packing Electric-Light Bulbs, of which the following is a specification.

Prior to our invention it has been common practice to slip electric light bulbs into sleeves formed of corrugated paper to protect them during transportation and handling, the wrappers being commonly made of somewhat greater length than the bulbs so that they extend a sufficient distance beyond the large end of the bulb to protect the rather delicate point of glass which occupies the end thereof and which, unless carefully guarded, is apt to be knocked off thereby destroying the seal of the bulb and permitting air to enter the same. It has also been common or usual to maintain the location of the bulb the desired distance within the end of the sleeve or wrapper by inserting in the end of the latter beyond the bulb a strip of corrugated board bent into annular form and of such length that when the inner edge thereof is in contact with the bulb the outer edge is approximately even with the corresponding edge of the sleeve or wrapper. In such construction the friction of this lining strip against the interior of the sleeve is depended on to prevent its dislocation and the pressure of the sleeve against the bulb maintains it in proper relation under ordinary careful usage provided the sleeve is of the proper size to exert the necessary pressure on the bulb. If, however, the wrapper does not fit sufficiently snugly or if in the handling of the package it is subjected to unusual jar in the direction of its length, the friction of the wrapper on the bulb and on the interior collar is apt to be overcome or the bulb to slip forward within the collar to a position to expose the fragile end of the bulb. Furthermore, in assembling the package considerable time of the operative is employed in adjusting the inner collar or spacing member and the latter is apt to fall out leaving the bulb free to slide forward in the sleeve.

It is the purpose of our invention to avoid the above difficulties and objections by providing a single-piece packing or wrapper which requires less handling and attention upon the part of tl e pecker and which will securely hold the bulb against longitudinal displacement of the bulb with reference to the wrapper.

In the accompanying draw igs have shown two preferred forms of the invention as described in the following specification. It is to be understood, however, that the specific disclosure is for the purpose of exemplification only, the scope of the invenion bein defined in the following claims in which we have endeavored to distinguish it from the prior art, without, however, relinquishing or abandoning any portion or feature thereof.

Referring to the drawings Figure l, is a perspective view of the preferred form of wrapper as it is furnished to the packer; Fig. 2 a perspective view of a bulb with the wrapper in position thereon, the wrapper being shown in section to disclose the interior; and Fig. 3 a perspective, partly broken away, of another form of the invention.

Referring first to the form of the invention shown in Figs. 1 and 2 the wrapper l is formed of corrugated board which'may be of the usual character and is of a sufficient length to provide for completely covering the bulb 5 throughout its length and to provide a lining or spacing collar 6. When the bulb is packed the collar 6 is turned in as seen in Fig. 2 against the larger end of the bulb, and in order to facilitate this operation the wrapper is slit along a line substantially parallel to its end and at diametrically opposite points as at 7 leaving intermediate the slits short unsevered hinge portions 8 so that the collar 6 when turned in remains an integral part of the sleeve. If desired, to facilitate the packing operation, the board is crushed or scored along the line of the hinge 8.

The packer in preparing the bulb for shipment first inserts it in the wrapper which then assumes a general cylindrical form and then taking the bulb with the wrapper thereon between his hands presses against the upper edge of the collar'portion of the wrapper in line with the hinge por tions with his fingers reversing or bending the collar inward, the latter readily yielding because of the above described slits. Thus the free edge of the collar is arranged to engage the bulb and prevent its outward movement in the sleeve. The connection of the collar to the sleeve tends to cause its inner end to stand out slightly from the wall of the sleeve and thus prevent the bulb slipping through the collar. It will be seen that the packing operation is greatly facilitated by our improvement, the necessity of handling two different articles by the packer being obviated and the collar automatically adjusting its position within the sleeve. By reason of the connection of the collar to the sleeve the former cannot drop out or become displaced.

Tie above described form of the invention is that preferred by us though certain of the advantages of the invention are realized in the form shown in Fig. 3. In the latter the tube instead of being slitted is simply scored upon the line where the end thereof is to be bent in and 'this scoring is carried entirely around the sleeve the sleeve and permitting the bulb to shift longitudinally of the latter.

lVe claim:

1. A wrapper for electric light bulbs consisting of a tube of corrugated board comprising a main portion and a collar portion permanently attached together upon a Weakened fold line. i

2. A wrapper for electric light bulbs formed of corrugated board and comprising a body portion and anintegral collar portion, such portions being partially severed from each other along the line of fold but integrally united by hinge; portions.

In a wrapper for electric light bulbs a tube of corrugated paper comprising a body portion and a collar portion the latter being partially severed from the former along the line of fold but connected thereto by hinge portions suitably scored. I

a. As an article of manufacture a package comprising an electric light bulb and a wrapper of corrugated board the latter consisting of a main sleeve and a collar integral therewith and folded to project interiorly of the sleeve and rest against the bulb.

5. As an article of manufacture a package comprising an electric light bulb and a wrapper therefor of corrugated board comprising a body portion surrounding the bulb and a collar portion integralwith the body portion at opposite points and partially severed therefrom along lines intermediate said opposite points. i
